Description

Method in UE in the cordless communication network, network node and the client node

Technical field

The disclosure relates to method, the method in the subscriber equipment and the method in the client node in the network node of cordless communication network.Specifically, the disclosure relates to for setting up the process of communicating by letter based on the information of the text message that sends from subscriber equipment between subscriber equipment and the client node.

Background technology

Short Message Service (SMS) was introduced in the 3GPP GSM series standard in 1985, was used for to the transmission of GSM cell phone and from the message of GSM cell phone transmission up to 160 characters (comprising the space).The system that SMS initial idea behind is to use phone to optimize is such as GSM, to be used for the message of control telephone service during the period when not having signaling traffic in the signaling paths transmission.What do not predict is the dramatic shift in the several years subsequently in the social behavior.Instant message transmission (IM) on the PC makes to be converted to away from audio call with its oneself specialized vocabulary than younger generation carries out text based communication.Afterwards, the entertainment service that adopts SMS to carry out enterprise, delivery of content and relate to SMS, for example TV ballot.In wireless market, used SMS to use (such as location-based moving advertising) in conjunction with various location-based services (LBS), for example be used for to the restaurant of institute's advertisement or near the mobile subscriber discount offered the arenas.The urgent call route entity also use location information to give suitably (public safety answering point) PSAP by the minimum delay with the urgent call route.

Strengthen messenger service (EMS) based on standard SMS, but have the format of adding text to.Format allows message to contain text, electronic card (vCard), electronic calendar (vCalendar) and the wireless vector graphics object of animation, picture, melody, format.This class object can be mixed together in the message.

In the 3GPP standard, SMS is the service of describing for public land mobile network (PLMN), and it transmits short message via service centre (SC) between GSM/UMTS travelling carriage (MS)/subscriber equipment (UE) and Short Message Entity (SME).SME is the entity that can send or receive short message.The interworking and the relay function that transmit as message between MS and SME under the SC normal condition.The exchange of short message between MS and e-mail server also supported in the SMS service, and this relates to Email to the gateway of SMS.

Point-to-point and the Cell Broadcast CB SMS service of 3GPP technical specification TS 23.040 regulations.Cell Broadcast CB (regulation in the 3GPP technical specification TS 23.041) is to allow definition text or binary message and it is distributed to the technology of all portable terminals that are connected to one group of residential quarter.Cell Broadcast Entity (CBE) is connected to CBC (CBC).Then, cell broadcast messages covers according to CBC and requires to send to the residential quarter from CBC.Senior infrastructure will be used for the used zone of definition based on the interface of GIS-Geographic Information System (GIS).

Comprise under the SMS normal condition for message and submit and receive specific 8 unit to:

The validity cycle (the indication effective period of short message, that is, carried out transmit to the recipient before SC will guarantee how long it is present in the SC memory);

Service centre's timestamp (short message arrives the time of SC);

Protocol identifier (to the reference of the more upper-layer protocol that using or with the interworking of a certain type remote information process device (telematic device));

The more message that send (being true when in that SC, one or more Messages-Waiting being arranged);

(whether the information unit that is provided by SC or SME is being priority message to the PLMN Indication message for priority; Should attempt the priority message transmission, and no matter whether MS has been identified as temporary transient shortage, or do not have idle memory capacity);

Messages-Waiting (is successfully transmitting under the situation of attempting owing to surpassing previous that the temporary transient movement that lacks or MS memory capacity causes, service unit makes PLMN that HLR, SGSN and VLR can be provided, and recipient MS is associated with following information with it: exist in the SC that starts and wait for the message that will pass to MS);

Alarm SC (service unit, it can provide to notify SC MS to be ready to again receive one or more short messages by some GSM/UMTS PLMN, make SC can-receiving the transmission cut-and-try process of alarm during SC-initiations for the queuing message that is sent to this MS); And

(service unit starts for verifying that message receives wherefrom MT correlation ID; When only being used in the HPLMN that receives MS and using SMS router or IP-SM-GW).

SMS can realize in different system and based on different technologies, such as the SMS by IP or the SMS by gateway (SG).

3GPP be at the research longer-lasting answers solving in the process for the needs of non-voice emergency services, but it may have for many years before available on the market at this longer-lasting answers.The people's of the unresolved ability of not having of this time range how instant needs.At recent buffering technique, exist to be used for SMS to 911 method for communicating.But they mainly focus in the interactive upgrading of supporting on the communication interface PSAP side, and unresolved end user's device, start wireless network and final SMS shortcoming and restriction (for example fail safe, stand-by period, route etc.).

These recent SMS to this type of of 911 methods one of may be alternative be, use and communicate by letter with the terminal type (TTY) of PSAP, do not require the user that independent TTY terminal is attached on their mobile device.This alternative being commonly called " TTY emulation ".Preferred circuit exchange emergency voice calls is set up in TTY emulation, and uses media path to transmit and receive character as TTY sound (normally Baudot sound).Emergency voice service is used in TTY emulation again, and it comprises high reliability, low latency, processed and further feature.Yet for the TTI emulation mode, one of challenge of recognizing is, generally speaking, replaces audible sound, and it is more reliable to transmit and receive signaling between travelling carriage and base station.

Another kind method is to dial audio call to 911, makes PSAP call out to obtain to identify the calling party that can not use speech and register at SMS; Then, PSAP calls out and obtains that calling party initiation of direction SMS text message.Owing to transmit the SMS that exists as the part audio call by the control channel that is associated, so this has eliminated some restrictions of SMS, transmits SMS because MSC there is no need to carry out " paging " process.In addition, owing to set up audio call, so the normal route of audio call and position capability can use, thereby eliminated some other restrictions of SMS.Some shortcomings of this method are SMS " storage and forwarding " character and the following requirements of inheriting: the user can read and send SMS when carrying out audio call, this is inconvenient and always not possible.

Another kind method is real-time text, and wherein the text is launched when the user keys in message character by character.Real-time text provide for storage and transmit the SMS system impossible functional-make dialogue be equivalent to voice dialogue, make and can closely follow dialogue, and the real-time interaction effect takes place.Real-time text requires the IP data to connect, because message is by the IP protocol transmission.Undefined such as abilities such as automatic route and location.

Announce that WO2009021556 (A1) discloses another method.According to this method, emergence message is used as suffix to be added on the emergency telephone number.Emergence message can comprise: the indication of position indication, the ability of voice answer-back, appended SMS, automatic alarm etc., and emergence message adds on the emergency numbers as suffix by phone.The Web portal node is looked after separating of the emergency numbers dialled and emergence message, so that connect and can normally set up by the urgent call of network to urgent center, at urgent center, emergence message is presented to the emergency operator.

Some problems of known method are described below.At first, in the subordinate of institute or standardized cellular network, there is not the based on network emergency services of transmitting based on message.Urgent location (for example the location of calling out for E-911 in the North America or in Europe for 112 location) is the rules and regulations requirements in the U.S..Usually by setting up urgent call, that is, someone dials emergency numbers (being 911 in this embodiment) at cell phone, triggers urgent location.Set up the voice communication between user and the public safety answering point (PSAP) then.This emergency services for example may be infeasible for the people of the ability of not speaking.And, under the situation that calling 911 is called out, problem may be arranged also, because cellular user is on the hazard, and impossible with the voice communication of PSAP client/agent.In fact this situation may stop user's calling 911 to get help, and for example obtains police's help.In addition, emergency numbers also may be because capacity limit and busy, for example under the situation of calamity, and than at message transmission service, much smaller at the voice call network capacity.

The other problem of prior art is not have possibility to guarantee sign and the transmission of calling party.At first, for example might practical joke (spoof) SMS message and make them seem mobile device from other people.Secondly, SMS is the service of doing one's best, and, might guarantee this transmission and any indication that obtains relevant SMS that receives or read from PSAP that is.

Another problem of prior art solution is that solution does not all provide the possibility of guaranteeing all to be routed to from all message (segmentation or unsegmented) of the SMS message sequence in the same emergent session same PSAP.Mobile device and network between two SMS that send from same mobile device all without any relevance, because SMS is discrete message.According to present appearance, if the subscriber moves to the another location, then SMS can be routed to different PSAP.

Summary of the invention

Present open some illustrative example and/or the embodiment that realizes.Although many in the following embodiment example are described for PSAP, this technology also is applicable to commerce services node or client.Owing to the similitude of the emergency of describing later, do not describe the embodiment of ordinary circumstance in detail, but those skilled in the art can understand the embodiment of ordinary circumstance easily.

According to an embodiment example, text message is emergency message, also is SMS in general sense, it comprise contain following at least one message: the text relevant with emergency situations, figure, video, multimedia etc.The emergency message content can be pre-configured, perhaps can follow predefined template.Emergency message also can comprise in following one or multinomial:

Session id namely is used for conversation-based emergency message transmission;

UE sign (for example SIM card sign or the information relevant with user profiles);

Device identification (for example type of device, device ID or unruled card ID);

Subscribe sign, for example the form that identifies with SIM card;

Urgent pointer is for example when being arranged to 1 or the binary system of indicating emergency situation during emergency numbers;

The UE type, for example travelling carriage, kneetop computer or PDA and their series, it for example can be used for dump energy and estimates;

Positional information;

The UE ability relevant with the location, the method for for example supporting, the frequency of supporting etc.;

The information relevant with power consumption and/or current battery energy level, for example remaining battery power (battery level) is as predefined designator (critical/low/in/height) or percentage or remaining time of accounting for maximum electric weight;

The language indicator relevant with the message language of preferred message language or use;

Communicate by letter with the end user and/or designator or one group of designator that locomotivity is relevant are included in the emergency message, for example limited (or not having) write/limited (or not having) say/limited (or not having) mobile, wherein this ability also can be relevant with ability or the user preference in the current situation;

At least one designator relevant with mode with the preferred means of communication or answer, for example identical/SMS, or other message transmission, such as voice contact, wherein " identical " infers, if be the SMS form to the communication of PSAP, then the response from PSAP will be the SMS form.

In example embodiment, during emergent session, send additional short condition message, for example pilot cell electric weight.This for example can carry out when reaching a certain battery threshold.The example of battery threshold is to be reduced to 50%, 25%, 20%, 15%, 10% etc. at every turn.

Thereby urgency communication is set up can comprise following steps: obtain positional information; Sign " suitably " PSAP; To suitable PSAP transmitting emergency message (have and/or not roaming, namely be with or without the change network); Language consistency between the suitable PSAP that guarantees the emergency message of launching and identify; Obtain the positional information of refinement or other positional information; And the callback or the SMS that carry out UE get back to UE.

Step listed above is not necessarily by carrying out with described identical order.Also not necessarily always need institute in steps.It is also understood that, although above step has only been described single two-way news exchange (for example get rid of and confirm), but between UE and PSAP, can there be a plurality of message, and can exist in a plurality of segmented messages or the message sequence of launching at least one direction, and the segmentation of (for example from UE) and a plurality of message are directed to same PSAP on same direction, and also can walk via same path at least some cases.

Be used for obtaining/obtaining the process of positional information.

Provided below about how obtaining/obtaining the example of positional information, wherein obtaining in emitting side of positional information carried out.

In known text message (SMS) process and definition, there is not positional information can be included in the text message signaling.Yet, be passed to suitably/preferred PSAP in order to ensure message, at least can obtain " roughly " positional information in emission before the message, wherein " roughly " positional information can comprise or available locating information or the positional information that can obtain fast in UE.This " roughly " positional information for example is to satisfy to require the positional information of guaranteeing that this positional information is not expired and not out-of-date sometime.This for example can realize by stabbing service time.Coarse position information (back only is called positional information) because available information is old, be the fact more than threshold of age of pass by or time and can not horse back available.The positional information availability depends on that UE ability and UE realize, although and just may be enough with this positional information in this step, in text message, can comprise high precision position, be the positional information (if available) of refinement.

Positional information can comprise in following one or multinomial:

The Serving cell identity;

The cell ID of one or more other residential quarters;

Network identity or network title;

The positional information of urban addresses form, this positional information position of UE not necessarily wherein, near but position or the radio node position of object also can describing, and positional information or receive from another node (for example eNodeB, MME, location node, femto gateway etc.) wherein, perhaps obtain from local data base, its conduct is based on the result of the localization method of UE.

Device location information, (latitude for example, longitude) or (latitude, longitude, highly, the level uncertainty, vertical uncertain, confidence level, speed, direction) set, wherein positional information is by localization method (GPS for example, A-GPS, GNSS, A-GSNN, OTDOA, UTDOA, AEICID, E-CID, CID) obtain, perhaps receive from network, perhaps obtain to be used as result based on the position fixing process of UE by UE, and can be included among the SMS, as text, figure, vector graphics for example, binary data, or have from the independent container of the positional information of another node reception, for example positioning result that transmits with the LPP positioning reporting.This device location information can be followed the position message form corresponding to one of 3GPP GAD shape.

A residential quarter (for example Serving cell) that is associated with cell identity or the radio signal of more residential quarters are measured, and for example receive signal strength signal intensity or received signal quality (but for example ought not have the positional information time spent, can launch these measurements).

The positional information of obtaining that is used for urgency communication or any other communication can be stored in UE memory 440.

In an example embodiment, the positional information of obtaining is included among the SMS that will be transmitted into indicated PSAP, perhaps as a part (for example multi-object) text message (SMS), or is included in the SMS signaling.In another embodiment, at least at conversation-based emergency services, but also might be at the service of sessionless (for example when message follow same path or same destination when being guaranteed), redundant position information (i.e. the positional information of not upgraded as yet since the last emission of positional information in same session) is not by signaling and be not included in next text message.In one embodiment, this is applicable to next text message that is transmitted into the same emergency numbers in the same emergent session, and it is used for conversation-based emergency services.

In this example embodiment, with among time/date and time information, Serving cell ID and the tracing area ID at least one come mark be included in the text message (SMS) or be associated with text message (SMS) or in conjunction with the positional information of signaling.This mark or can perhaps also can be added among first radio network node (RBS) or the MME at emitting side (UE).In an example embodiment, the positional information (being positioning result) that is included among the SMS is proved conclusively under the situation of having considered time/date and time information by network node nearest relatively Serving cell ID and tracing area ID subsequently.Serving cell ID mark or tracing area ID also can be used for the destination PSAP in sign/definition interdependent node (i.e. the most suitable client node).

In this example embodiment, when the text message of launching (SMS) contains designator, when for example containing urgent designator, is added with positional information/add the marking (stamp) for text message with positional information in network node 300 place's text message.In an example implementation, positional information or urban addresses form, for example as described therein, perhaps it is the Serving cell id information.In another example, network node 300 is eNodeB or MSC or gateway node (for example femto gateway) or routing node or MME, and it is functional to comprise location node.

Text message is transmitted into " suitably " client node.

Provided the example how text message is transmitted into client node 500 below, client node 500 in most of the cases is the most suitable client node.

In one embodiment, client node 500, be suitable client node or suitably PSAP can be local PSAP, hithermost PSAP preferably, namely PSAP selects based on geographical principle.By contrast, UE may only understand maximum PSAP, and thereby by in text message, indicating ownership PSAP to be routed to ownership PSAP.Ownership PSAP may be incoherent for service is provided, particularly when UE for example roams in another network and long-range geographic area.Therefore, in this example embodiment, this positional information is used for routing messages to suitable PSAP, and it not necessarily belongs to PSAP, but may be ownership PSAP.In a specific example, the positional information of city form or cell ID are used for route.

In addition, PSAP select to be embodied as in the network node 300 or client node 500 (PSPA) in mapping function, wherein this mapping function will be mapped to PSAP from all or some information that text message obtains, and wherein this information can comprise one of following item or any combination: preferred means, positional information, language indicator, ownership PSAP designator and end user's ability etc. of type of message (for example SMS or MMS), communication.PSAP ability and the present situation, for example PSAP load situation also can be considered in this mapping.

In an example embodiment, this mapping is implemented in the Centroid of service MSC or MME or CSCF node or IP gateway network node or SC or general processing messages transmission service, and it is not limited to known SC.Thereby this mapping can be embodied as distributed functionality.

In another example embodiment, during setting up, the session of emergency text messages service carries out this mapping.In another embodiment, if possible do not set up conversation-based communication, then carry out mapping for each independent text message (SMS).

In case should mapping known, then text message and the positional information that is associated with this session just must be routed to same PSAP.A kind of mode that realizes this respect is to comprise PSAP sign/designator in all text messages, comprises the response message that is associated with same user ID and/or session id.This mapping result (be PSAP sign) also back signaling give the starting point of first text message or the starting point that signaling is given session initiation message, for example with text message or session affirmation or text message confirmation of receipt.The PSAP that shines upon can be stored in (for example with user ID) in the mapping node then, and/or is stored among the UE.The latter will allow UE to comprise the PSAP that shines upon, and be used as sending to the destination in its outgoing message of emergency numbers.

Described the PSAP in this part in the early time, it is selected based on geographical principle.In more complicated method, can use one group of PSAP, wherein these PSAP can be connected to maybe and can be free of attachment to gateway or routing node, for example referring to Fig. 9 a-c, even in the same area, but wherein PSAP distinguishes by a certain standard.The example of this standard can be language, wherein indicate the text message from the language of for example pre-configured a certain group to be directed to a PSAP node, and indication is directed to another PSAP node from the message of the language of another group, and wherein this indication can be the code speech designator relevant with this message language, and wherein this designator also can be indicated the Preferred Language of response message.PSAP also can distinguish by their ability, and their ability for example is to handle communication of text messages, the ability of voice, multimedia or mixing only.In one embodiment, PSAP itself can be that gateway or router are directed to suitable interface with calling and the message that will be received.Notice that although use term PSAP in this illustration part, client node can be the client node of any other type, and is not limited to PSAP.

Fig. 9 a illustration the example of PSAP (solid line) embodiment, and wherein in network, for example roam selection by network node or routing node.According to this illustration, pass through radio access network (RAN) from the text message that UE receives, and just be routed to suitable PSAP by network node 300 at core network.

Fig. 9 b illustration the example of preferred PSAP (solid line) embodiment, and wherein PSAP selects by PSAP gateway (GW) for example by comprising the functional network node 300 of PSAP GW or being undertaken by comprising the functional client node 500 of PSAP GW.According to this illustration, pass through radio access network (RAN) and core network from the text message that UE receives, and be routed to suitable PSAP at PSAP GW.

Fig. 9 c illustration the example of preferred PSAP (solid line) embodiment, and wherein PSAP selects to be undertaken by GW, and communication/connections that voice are only arranged is via the independent PSAP of PSAP router arrival.Notice that network node 300 can comprise the functional and/or PSAP router functionality of GW, client node 500 is also like this.According to this illustration, pass through radio access network (RAN) and core network from the text message that UE receives, and be routed to suitable PSAP according to communication request/possibility.

When text message successfully was delivered to PSAP, PSAP can confirm the fact that the text message that receives or it have been read by PSAP agency/client.When receiving/reading the PSAP text message, UE also can send affirmation.

Subsequently, based on Serving cell ID positional information the PSAP mapping method is described in more detail.In each text message service center (SMSSC) (general meaning by it), preserve and search/mapping table, be used for making the PSAP of Serving cell ID coupling appointment, and for example dynamically update this look-up table based on optimum route and load information.When text message is sent to maybe will send to symbolic number (for example " 911 " or " 112 ") or contain urgent pointer the time, use coupling.Based on this look-up table, Serving cell ID is translated into the address of local PSAP.As long as UE is connected to same SC and PSAP or proceeds to same SC and the communicating by letter of PSAP, then for a plurality of short messages transmit, emission and ACK message will keep comprising the same paths of destination again.In one embodiment, keep identical destination in the same session in the inherent a plurality of sessions of given interval (for example a day).

Language consistency example

Can use the language certain content, in order to determine the language consistency, such as: the body of text in the text message from UE to PASP; Body of text in the text message from PSAP to UE; Signaling or be included in positional information in the text message; And/or in another node, add the positional information (when it can be identified as emergency message) of the marking for text message.

At least relate to UE 400 and PSAP 500, but also can relate to another network node 300, its available position information adds the marking to text message (emergency message).Between all nodes that relate to, need to guarantee the language consistency.In order to make this respect become possibility, can use the language indicator in text message or the signaling that is associated to come alignment request-response language, for example, PSAP response acquiescence is the language of indicating with in the reception text message.This can carry out at least in two ways.Use a kind of mode, PSAP provides response message with institute's requirements language.Use another way, PSAP provides response message with the language that PSAP supports, and translate this message in the translation node (for example PSAP outbound interface) or at network node 300 places therein, wherein this translation node need be known language and the expectation language of text message.If use two these type of language indicator, the translation node that then has a translation ability at first can check translation whether necessary (by these two designators relatively), and check then whether translation node supports to expect language, check the language of supporting perhaps the other way around-at first, and check then whether translation is necessary.If sign is for needs and the possibility of translation, then old text is replaced by the text of translation, and is delivered to next node in this path.Otherwise, do not transmit this message with changing.In one embodiment, select the path to guarantee the needing message of translation by having at least one network node of translation ability.In another embodiment, when selecting the path, the load of translation node is taken into account.

Also can during session is set up, namely for conversation-based emergency services, between PSAP and UE, consult or transmit language.If there is language conflict, can consider that then PSAP remaps, identify another suitable PSAP for example by PSAP request network node 300 repetitive processes, or by PSAP.Alternatively, select PSAP, make language conflict be avoided.

Positional information process and the information of refinement.

In example embodiment, when the positional information that receives does not satisfy some and requires, for example time requirement, such as the time of for example pass by from indicated time to the current time of timestamp above a certain threshold.Other requirement that may need to satisfy for example is accuracy requirement, and for example the uncertainty of available position information surpasses a certain threshold, and the confidence level that perhaps is associated is below a certain threshold.When these require not satisfy, then want the triggered location session, for obtain/obtain/retrieve the positional information of refinement.This can carry out based on aperiodicity or periodic location reporting process.

In another example embodiment, configuration cycle property positioning result report in UE, network node or PSAP, i.e. the location information report of refinement, and be somebody's turn to do periodically based at least one in the following item: UE speed and UE power consumption/energy content of battery information.The UE positional information of refinement may also be provided when sending text message, that is, and as positional information.UE 400 can be configured to always report UE speed, or report UE speed when request.In another embodiment, can come updating record periodically based on the UE speed of report, simultaneously battery energy level/capacity be taken into account, for example, preferably avoid cycle report frequently for the UE with critical low battery electric quantity.

In one embodiment, for the request of the UE positional information of refinement for example by PSAP or network node emission, this request can comprise predefined parameter set: the location QoS of urgent client type, COS, request, and wherein also can indicate the set of preferred orientation method or localization method, etc.The preferred set of indicated localization method can be relevant with UE ability and/or power consumption/energy content of battery, for example may be not too preferred based on the location of GPS or GNSS during at critical low electric weight when battery electric quantity, and based on network location may be more preferably.UE power consumption/energy content of battery relevant information also can be included in the UE positional information of refinement, or as UE ability signaling in location sessions.

In another embodiment, if provide UE to measure with SMS, then also the UE measurement is sent to location node, for example sent by PSAP or MSC.The positioning result that obtains is passed to PSAP or network node as the UE positional information of refinement, and is further processed.The UE positional information of this refinement also can be included in the response message.If this positional information urban addresses form then needs to guarantee the language consistency with message content.This be for no other reason than that can use a certain language typing address, and therefore may need translation.

Be in the urgent support of " connection " and " free time " state.

For the emergency text messages transmission of sessionless, guarantee that UE 400 is in " connection " state when the location sessions of UE positional information of refinement is obtained in initiation.If UE comes " free time " pattern after contact PSAP or urgent center, then can trigger the surveying record that is in " free time " pattern.This group is measured and be can be used for the location subsequently.For the emergency services of discussing, can pre-definedly should group measure and recording configuration, for example RSRP of N best cell.In another embodiment, when measuring plan support emergency services, in the measurement in " free time " state and the recording configuration UE power consumption and/or the energy content of battery are taken into account.

In another embodiment, contact PSAP or urgent center were associated the period of stipulating with emergency services after, UE was in " connection " state.Network can not initiate to connect dispose procedure then to the UE that is in " connection " state, till the timer that is associated with the defined period then.

In another embodiment, when PSAP for example receives SMS and determines that UE is not in " connection " pattern, paging UE.UE is not in determining and can being undertaken by PSAP of " connection " pattern, for example by obtaining information or Location Request fault from the network node (for example RNC the WCDMA, or the eNodeB among the LTE, or the MME among the LTE) of following the tracks of the UE state.For example, if in network not the information about the RAN that uses before can use, RAN(or acquiescence that paging starts from many RAT of UE most recently used system are LTE), realized many RAT emergency services thus.If the location is optional for emergency message, then when it is necessity, namely identify UE and be not in " connection " state, the PSAP that then receives SMS message will trigger the UE paging, namely pass through before the beginning location sessions to network node (for example MSC or MME or IP routing node or gateway or the SM) signaling of being responsible for or transmission message.Otherwise, when the response message that sends to UE from PSAP arrives the node of being responsible for, can trigger paging automatically.

Callback process, communication is set up.

In this embodiment, can use as underflow indicator, that is, the designator relevant with mode with the preferred means of communication or answer judges that PSAP will contact the mode of UE.And, also language indicator can be taken into account at this.When setting up session, then PSAP can select/consult any means to contact back UE.But PSAP callback UE, even under the situation that does not still have session to set up.Yet, be primary by the preferred communication mode of UE indication at this.When ring/vibration is unacceptable for UE, sets up calling and will not cause any ring/vibration.PSAP is responsible for asking this call session, for example by sending request to another network node (for example MSC or MME).In case UE is on Traffic Channel, then PSAP just should be able to carry out the MT-LR of urgent client type.

Can realize stopping ring (barring ringing) by different way, or any specific alarm configuration.

Example 1: definition " the E-911 ring stops " information unit (for example having the binary value corresponding to " opening " or " passs ") in the network communication protocol between PSAP and network node wherein is used for guaranteeing the ring that stops the UE from the information of IE acquisition by network.The higher level signaling of UE origin automatic network node or radio network node (for example eNodeB) is notified, and correspondingly configuration is used for the ring of callback, wherein this network node or receive this information from another network node or from PSAP.

Example 2: designator is comprised in the text message that is transmitted into UE, wherein this for example comprise can be by adding predefined label in the text message title to, its definition message enter warning.

Example 3:PSAP sends client type and/or the service type information corresponding in question emergency services type, and this has further determined the UE configuration, and wherein client type or service type information are delivered to UE via a plurality of network nodes.Alternatively, for this designator of explicitly signaling, the predefined radio bearer configuration that comprises the ring that stops can be associated with client type and/or COS.Can use client type designator and/or COS designator at this.

Example 4: can come entering in the configuration UE to connect alarm by Session Initiation Protocol or other similar functions agreement.SIP is the signaling protocol for the ietf definition of control multimedia communication sessions (calling out such as the voice and video on the Internet Protocol (IP)).Thereby, with the sip message form be extended to can be used in the configuration at least one reticent emergency mode be the example of another embodiment.

In network node or by PSAP, ring stops that designator can judge based at least one in following: for example UE preferences/capabilities described above, client type (client type that for example disposes or new predefined client type can be associated with the emergency services based on non-voice) or COS (COS that for example disposes or new predefined COS can be associated with the emergency services based on non-voice).

Can dispose alarm of vibration, screen light, message informing, any kind etc. with the mode that is similar to above-described ring process.Also can collect an assembly in predefined configuration profile and put, this profile can this locality be stored among the UE or from network and receives.This profile can be associated with the emergency services type.This profile also can dispose in UE via user interface by changing default setting.

This technology relevant with UE on the other hand, wherein UE preserves at least one profile (local storage or receive from network), and its configuration is used at least one and promptly enters connection.This connection is associated from the message of PSAP, calling, multimedia etc. with receiving to start.Enter alarm configuration and become to be in reticent emergency mode, for example do not have ring, minimum sound or light alarm etc.This profile is configured and is used for specific emergency services type, connection type, and/or according to described UE preferences/capabilities in the early time.Specific emergency services type for example can be based on emergency services or the non-voice of non-voice and initiate the emergency services of (initiating from UE).

With the example embodiment in the lower part and the same LTE that is not limited only in other parts, and be applicable to user and control plane.The problem of existing method is, only exists a client type to be used for emergency services, and this may be inadequately when disposing different emergency services types (for example urgent call and text based emergency services) in network.Therefore, in an example embodiment, this group known client type is expanded by at least one new client type, to consider the emergency services of newtype.In another example embodiment, independent client type is used for only having the emergency services of emergency services, text based emergency services and the mixing of voice.Also may exist independent client type to be used for Multimedia Message and transmit emergency services.In another embodiment, known emergency services type is expanded, and to consider the emergency services of newtype, for example new COS is defined the emergency services of transmitting or mixing for the text based Multimedia Message.

Can be along any interface existing or disclosed herein and between relevant network node (directly or via one or more other nodes) for example at MME and location node (E-SMLC in the control plane or the SLP in the user plane), E-SMLC and SLP, location node and LMU (location measurement unit that is used for UTDOA), LCS client and MME/MSC/GMLC, between GMLC and the MME/MSC the new client type of signaling and or COS at least one the new encoded radio of LCS client type or LCS service type information unit (for example as).The agreement that is used for above-described interface strengthens the LCS application protocol (LCS-AP) that for example uses, the radio access network applying portion (RANAP) on the Iu interface among the UTRAN with described new signaling between MME and E-SMLC.

The client type of new signaling and/or service type information can for example be used for distinguishing voice emergency services and non-voice emergency services by receiving node, for example location node, PSAP or by network node, may also have different priorizations, localization method selection etc.

In addition, be noted that be included in network node 300, UE 40 and the client node 500 described among circuit 310-340,410-440, the 510-540 some to be regarded as independent logic entity respectively, but independent physical entity not necessarily.Only lift an example, the processor circuit 330 of network node 300 and language determine that circuit 340 can be included in or cooperative arrangement in same physical circuit.
